疲劳设计规则的使用提供了避免焊接结构疲劳失效的最有效方法。本章概述了现行规则的基础以及如何在不同规范中应用这些规则，包括考虑残余应力、尺寸效应、材料、焊接工艺和环境。需要进一步研究的领域突出，包括适应目前的规则与有限元应力分析，局部应力方法的发展，复杂的加载和累积损伤计算的治疗。
: The use of fatigue design rules offers the most effective means of avoiding fatigue failures in welded structures. This chapter outlines the basis of current rules and how they are applied in different specifications, including consideration of residual stresses, size effect, material, welding process and environment. Areas needing further research are highlighted, including adaptation of current rules for use with finite element stress analysis, development of local stress approaches, the treatment of complex loading and cumulative damage calculations.
